According to a press release put out by Hyatt, the hotel has confirmed that there has been unauthorized access to payment card data from cards used at certain locations within Hyatt’s chain of hotels, such as at its restaurants between the 13th of August to the 8th of December, 2015. Other locations include the hotel’s spas, golf shops, parking, and even at the front desks, although they do point out that these locations represent a small percentage of at-risk cards.
Based on the list of hotels that have been affected, it seems that there are around 250. If you have stayed at a Hyatt hotel recently, maybe you should check the list to see if that particular hotel is affected by the malware.
According to Chuck Floyd, global president of operations for Hyatt, “We have been working tirelessly to complete our investigation, and we now have more complete information that we want to share so that customers can take steps to protect themselves. Additionally, we want to assure customers that we took steps to strengthen the security of our systems in order to help prevent this from happening in the future.”
In the meantime just to be safe, you might want to review your payment transactions in the following months just to be sure that nothing suspicious is going on.
